Abstract

A uranium silyl compound, (Ar[^(t)Bu]N)_(3)USi(SiMe_3)_3 (1; Ar = 3,5-C_(6)H_(3)Me_(2)), has been synthesized, isolated, and characterized structurally and theoretically; compound 1 crystallizes in the space group P3̄ and its U−Si interatomic distance was found to be 3.091(3) Å. Geometry optimizations were carried out for the model systems H_3EU(NH_2)_3 (E = C, Si, Ge, Sn) with a set of reasonable constraints; calculated U−E distances and bond energies are in good accord with experimental data.
